Unable to listen on Firefox / Fedora Linux 27

[_calm_bomb_]

I reinstalled Fedora 27 on my laptop and started from scratch. I'm using Firefox 59.0.2 (64-bit). I enabled DRM and Winedevine plugin, but I'm not able to listen to any music - when I click play on a song, it shows as playing, but nothing happens, there is no progress in the time progress bar.

Anyone can help with this?

I solved this problem. I had to have media.autoplay.enabled set to 'true' in about:config.
